I have a semi-transparent monochrome image in a Photoshop document, that I would like to become fully opaque:
The opacity is already set to
Blending Options, it's just that this image has an alpha channel that I would like to remove.
How can I do that?

I know this is an old question, but it's the first result if you search for removing the alpha channel in photoshop and neither of the answers worked for me.
To remove the alpha channel, click Layer->Layer Mask->From Transparency, then right click on the mask in the layer pallet and select Delete Layer Mask.

It sounds like your issue is that the icon and opacity are baked into the alpha channel. This means you can't easily separate the two by duplicating the layer many times.
There's an easy solution though.
Command-click the layer thumbnail to make a selection based on the alpha (Photoshop may complain about not selecting pixels over 50%... ignore it).
Select → Save Selection, then press return (this will save the selection as a new channel.
Select → Deselect.
Open the Channels panel and select the one you just created.
Press Command-L to open the Levels window.
That's probably as close as you're going to get to retrieve the icon. From here, you can:
Command-click the channel thumbnail to make a selection.
Open the Layers panel and crate a new bitmap layer.
Fill it with colour.

There is a possibility not to Save as but
Export as and then is there a checkbox Transparency and you have to uncheck it, then it has no transparency :)
Big thanks to Adobe for their proffessionality that they leave Save as dialogue window without possibility to uncheck it there too :(

You can't have an opaque image with a transparent background. If you need to eliminate transparency but you have a specific background color that it needs to sit on, just add that color on a layer below
before you flatten.
If there really is an alpha channel that you'd like to delete, then you just drag that channel to the trash icon in the channels panel.

when you save the file you can choose in the -save as- window the the little i- icon(right side of the format pull down
. Here you can uncheck the alpha channel before saving....

Just save the image as jpeg then open it in another session and save again as png if you need to.
